AMOS S. BLAKE, OF WATERBURY, CONNECTICUT.

Latas Patent No. 84,162, dated Notember 1,7, 186s.

To all whom it may concern:

Be it known that I, AMos S. BLAKE,-of Waterbury, in the county of NewHaven, and State of Connecticut, have invented a new and usefulImprovement in Locks and I do hereby declare that the following is afull,

clear, and exact description thereof, which will enable others skilledin the art to make and use the-same, reference being had to theaccompanying drawings,

'forming part of this specification, in which- Figure l is a sidesectional View of my invention,

l taken in the line x a', fig. 2.

Figure 2 is a horizontal section of the same, taken in the. .line y y.

Similar i'etters of reference indicate like parts.

This invention relates to a new and improved lock,

inoperative, or incapable of being opened or unlocked on account of ice,objections which attend the use of the ordinary padlock;

In the accompanying sheet `of drawings, A represents what may be termedthe frame of the lock, which is of curved form, as shown clearly in tig.l, and has a straight spindle, B, cast with orattached to it at itslower end, the upper part, ax, ofthe frame being curved in such a manneras to project downward in line with the centre of the spindle B, but atsome distance' above it. A

C is a cup, which is fitted on the spindle, so that it may be moved upand down thereon, the. spindle having a rib, a, on its exterior, whichis fitted in a notch,

`b, in the cup, the rib and notch preventing the cup from turning on thespindle. l

Within the upper part of the cup C there is fitted a catch or pivotedbar, D, which, when the cup is raised to its fullest extent, .proj ectsover the opening in the lower part of theA cup, in which the spindle B lor bar D, having a tendency to keepthe latter in this position, as willbe understood by referring to iig. 2.

. E represents a cone, the lower end or base of which is attached to theupper-end of the cup C. f

This cone is hollow the greater part of its length,.in

order that it may receive the spindle B, and said cone has a rod, d,fitted centrally in it, to serve as a keyguide, the spindle B having akey-hole, bx, extending through it its entire length, as shown in g. 1.Y When the cup C is fully raised on the 'spindle B, the upper end of thecone E is in contact with the end of the curved upper part ax of theframe A, the end of ax being made conical, to iit into a recess in theupper end of the cone.

When the cup and cone are thus elevated, as shown in fig. 1, the lock isin a locked state, the cup and cone being retained in that elevatedposition by the catch or bar D, which is turned aside by the key F, sothat the cup and cone may be pressed down, in order to unlock the lock.`

This lock is extremely simple in construction, and cannot be damaged bywater passing into it, nor be encased with sleet and ice in winter, sothat it cannot be opened or unlocked, objections to which the ordinarypadlock is liable.

Having thus described my invention,

I claim as new, and desire to secure by vLetters Patent- The frame A,provided with the spindle B, in combination with the cup' C, providedwith the catch or.

bar D, or its equivalent, and the cone E, attached to the cup, allbeingconstructed and arranged substantially as and for the purpose specified.
